How to Change a Car Tail Light Bulb in Easy Steps
A burned-out tail light reduces visibility and may result in a traffic citation. Replacing the bulb is usually a quick DIY job, but the access method and bulb type vary by vehicle. Check your owner’s manual before starting.
Use your vehicle’s year, make, and model to find a compatible replacement bulb. Depending on the car, you may also need gloves, a Phillips screwdriver, a socket wrench, or a trim-removal tool. Turn off the engine and exterior lights before working.

Open the trunk or rear hatch and locate the access panel behind the affected light. Remove the panel, fasteners, or carpeting as needed. Some vehicles require the entire tail light housing to be pulled outward after removing retaining screws or nuts.
Rotate the bulb socket counterclockwise and pull it from the housing. Remove the old bulb by pulling it straight out or twisting it, depending on the socket design. Install the new bulb without touching its glass with bare fingers, then lock the socket back into place.
Turn on the parking lights and test the brake pedal, turn signal, and reverse light where applicable. Once operation is confirmed, reinstall the housing, fasteners, and interior access panel. For vehicle-specific details, see the complete guide on how to change a car tail light bulb.
Replacing a tail light bulb is easy on many vehicles and often takes 10 to 30 minutes. Difficulty increases if trim panels or the complete light assembly must be removed.
AutoZone may help install a tail light bulb when access is simple, but installation is not guaranteed. Ask the local store because staffing, vehicle design, and service policies vary.
The taillight and brake light may use the same dual-filament bulb, with each function operating at a different brightness. Other vehicles use separate bulbs or integrated LED units.
O’Reilly Auto Parts may assist with a tail light bulb if replacement requires minimal disassembly. Contact the store first to confirm whether help is available for your vehicle.
You can replace just the tail light cover only when a separate compatible lens is available. Many modern assemblies are sealed, requiring replacement of the entire housing.
Replacing the plastic over a tail light can cost roughly $20 to several hundred dollars. The price depends on whether a lens-only part is sold or a complete assembly is required.
